If the use of the cycle is required, and the only other path is the
road, then putting bicycle=no on the road will cause routing
algorithms for cyclists to push the cyclist to the adjacent cycleway.
When a cycle specific map gets rendered, then it could grey out the
road, with the cycleway highlighted. I think this is a better way to
tag it, otherwise routing will not know which road cyclists are not
meant to use.
I would also like to see the value bicycle=dismount, for short
sections where cyclists have to dismount as part of the cycle network.
